20090268727 | Early header CRC in data response packets with variable gap count - A method is provided for processing a command issued by a processor over a bus. The method includes ( | 10-29-2009 |
20090268736 | Early header CRC in data response packets with variable gap count - A method is provided for processing commands issued by a processor over a bus. The method includes the steps of (1) transmitting the command to a remote node to obtain access to data required to complete the command; (2) receiving from the remote node a response packet including a header and a header CRC; (3) validating the response packet based on the header CRC; and (4) before receiving the data required to complete the command, arranging to return the data to the processor over the bus. | 10-29-2009 |

20130242985 | MULTICAST BANDWIDTH MULTIPLICATION FOR A UNIFIED DISTRIBUTED SWITCH - The distributed switch may include a plurality of chips (i.e., sub-switches) on a switch module. These sub-switches may receive from a computing device connected to a Tx/Rx port a multicast data frame (e.g., an Ethernet frame) that designates a plurality of different destinations. Instead of simply using one egress connection interface to forward the copies of the data frame to each of the destinations sequentially, the sub-switch may use a plurality of a connection interfaces to transfer copies of the multicast data frame simultaneously. The port that receives the multicast data frame can borrow the connection interfaces (and associated hardware such as buffers) assigned to these other ports to transmit copies of the multicast data frame simultaneously. | 09-19-2013 |

20150063348 | IMPLEMENTING HIERARCHICAL HIGH RADIX SWITCH WITH TIMESLICED CROSSBAR - A method and system are provided for implementing a hierarchical high radix switch with a time-sliced crossbar. The hierarchical high radix switch includes a plurality of inputs and a plurality of outputs. Each input belongs to one input group; each input group sends consolidated requests to each output, by ORing the requests from the local input ports in that input group. Each output port belongs to one output group; each output port grants one of the requesting input groups using a rotating priority defined by a next-to-serve pointer. Each output group consolidates the output port grants and allows one grant to pass back to an input group. Each input port in an input group evaluates all incoming grants in an oldest packet first manner to form an accept. Each input group consolidates the input port accepts and selects one accept to send to the output port. | 03-05-2015 |
20150207637 | MULTICAST PACKET ROUTING VIA CROSSBAR BYPASS PATHS - An approach is described for routing data to a plurality of output terminals via a integrated switch router including a crossbar switch having both a crossbar and a plurality of crossbar bypass lines. Whereas the crossbar may connect each input of the crossbar switch to each output of the crossbar switch, each of the plurality of crossbar bypass lines may connect a single input of the crossbar switch to a corresponding single output of the crossbar switch. According to such approach, a replicated copy of a multicast packet may be forwarded to an output terminal via a crossbar bypass line in parallel with other data forwarded via the crossbar, thus increasing integrated switch router bandwidth. | 07-23-2015 |
